.To .all whom-it may concern.'

Be it known that I, JACOB I-InNDRionsoN,

a -citizen of the United States, .residing at Northport, in the countyof Stevens and State of Washington, have invented a new and usefulPermutation-Padlock, of which ithe following is a specification.

rThe present invention appertains to a permutation padlock, and .aims toprovide Va -novel and limproved device of that character.

It is-the object Aof the present invention to provide -a' permutation orcombination padlock, embodying a shackle and manually controllabletumblers within the padlock case, for normally maintaining the shacklein closed position, and for permitting the shackleto be slid when lthetumblers are set properly.

A further object` of the present invention is to provide a :padlock ofthe nature indicated, wherein means-are provided whereby.

vchanges in the combinations of the tumblers may be eii'ected ina simpleand convenient manner.

With the foregoing and other-objects in view, which will appear as thedescription proceeds, Vthe invention resides in the combinationand-arrangement of parts and in 0 lthe details of constructionhereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed can be madewithin the scope of what is claimed without departing from the spirit ofthe invention. The invention has -been illustrated in its preferredembodiment in the accompanying drawing, wherein of Fig. -2.

In carrying out the present invention, there is provided a ysuitablepadlock case 1, which has its sides orfaces, bottom and top split ordivided, to provide the ytwo sections 2 and 3, which have their bottomor lower end portions hinged together, as at E4, whereby the sections ofthe case may be :swung open and closed. 'The lower end or lbottom.portionof-the--section 3 preferably projectsl 'beyond the-sideor backportions,

.asnseen :in Fig. l', whereby the face or side portions of the section 2may overlap the saidprojecting lower end or bottom portion when thesections are .closed or folded together, l

The face -orside portions of the section 2 are preferably larger orgreater in extent, than those of the section 3, the sides or faces yofthe case being divided at one side of the center of the case to` thatend. Spindles or arbors v5 are journaled through the 'face or sideportions of the section 2, centrally of the case, and have lknurledheads or knobs 6 at their outer or remote ends for permittingthespindlesor arbors to be readily rotated Aby hand.

Secured .to the inner ends of the spindles or arbors 5i, is a pair oftumbler disks 7, which have the inner bosses or hubs 8 keyed or.otherwise engaged upon the inner ends of the-spindles, it beingpreferable to pro- -vide the bosses o r hubs 8 with square or non-.circular vopenings engaging over the squared 0r non-circular inner endsof the spindles 5. The .tumbler disks 7 are provided with :the inturnedor inwardly projecting marginal or peripheral flanges 9 which have theiredges spaced slightly apart, each of the flanges or lips 9 beingprovided with a chordal notch or slotyfl() for the purposes which willhereinafter appear.

A dial disk 11 is mounted rotatably upon each of the vspindles or arbors5, between the corresponding tumbler disk 7 and face or side of thecase, the dial disks being slightly larger in diameter than the tumblerdisks, so that their peripheral vportions project beyond the tumblerdisks. The outer or remote sides ofthe dial disks are provided withgraduations or indicia along the Inargins or peripheries of the saiddisks, and the face or side portions of the section 2 of the ca-seareprovided with openings or slots l2 adjoining the upper end or top ofJche case, through which the graduations or 1ndicia are visible from theoutside, for enabling the tumbler disks to -be set properly, as willhereinafter more fully appear.

In order to adjustably connect the dlal disks 11 tothe tumbler disks 7each of the dial disks is provided with an annular serres of apertures13, which .are confined within the faces or sides of the case, when thecase is closed, ascrew or key 14 being passed :through one ofthe.aperturesl-B of each dial disk and takinginto the threaded aperture 15provided in the corresponding tumbler` disk. lt is evident, at thispoint, that each of the dial disks is made fast to the correspondingtumbler disk, by thel clamping screw or key 14, whereby the dial diskswill be rotated with the tumbler disks, when the 'shafts or spindles 5are rotated. It will also be evident that by withdrawing the screws orkeys 14, the dial and tumbler disks may be rotated or swung with respectto one another, in order to change the combinations as will hereinafterappear, the screws -or keys 14 being passed through the proper-apeitures 13 so as to again engage he apertures 15 of the tumblerdisks. Y

The free end or top portions of the sections 2 and 3 of the case, areprovided with interengaging or intertttingv lugs or projections 16whereby, when the sections are closed, they will be locked againstspringing or shifting laterally relative to each other, which would beobjectionable.

. A latch o-r catch 17 is pi `otedl upon the free end or top of thesection 2, adjoining one face or side portion thereof, and is adapted toswing over the upper end or top of the section 3, when the two sectionsare swung together, to thereby retain thecase in closed condition, underordinary conditions.

The shackle 18 of the padlock, is of U- shape, and has a reducedextension 19 at one end which is' insertible into or through the socketor aperture 20 formed in the upper or free end of the section 2,- theextension or finger 19 being relatively short, so as not to engage thetumbler disks when the extension 19 is inserted through the aperture 20.Projecting from the other end of the shackle 18, is a relatively longprojection or shank l21 which passes through an aperture or bore 22formed in the upper end or top of the section 3 of the case, and whichhas its sides flattened, as at 23, from a point spaced from the end ofthe shackle 18, to apoint short of the free end of the shank 21, toprovide the head or shoulders 24 at the free end of the said shank. Theshank 21 is lprovided with a longitudinal slotl 25, and a retaining pin26 is engaged through one side of the section 3 adjoining its upper end,in order that the yinner end of the pin 26 will engage theslot 25 so asto permit -the shackle to slideA inwardly and outwardly to a limitedextent, but `preventingthe shackle from being removed, unless the pin-26 is withdrawn.

The projection or shank 21 is of such a length that the head orshouldered portion 24 is proj ectable through the slots or notches 10 ofthe tumbler disks, when the said slots or notches are swung in alinementwith the aperture or bore 22, in order that the head or shoulderedportion 24 may lock within the flanges 9 of the tumbler disks undercertain conditions, that is, when the tumbler disks are so swung, thatthe slots or notches 10 are out of alinement with the aperture or bore22 to break up the combination.

In use, when the sections of the case are folded together, or closed,those portions of the dial and tumbler disks projecting from the section2, as seen in F ig. 1,y will be housed within the section 3, thegraduated portions of the dials being exposed through the openings orslots 12 in the sides or faces of the case. When the tumbler disks areswung to the proper positions, whereby the channels or slots 10 alinewith the aperture or bore 22, this being readily accomplished bybringing the proper numerals or indications within the openings 12, willenable the shackle to be opened and closed. Thus, supposing the shackleto be opened or slid outwardly, the projectionor finger 19 beingdisengaged from the aperture or socket 20, and the projection or shank21 being drawn outwardly out of engagement with the tumbler disks, toclose or lock the shackle, it is merely necessaryto slide or force thesame inwardly so that the projection `or finger 19 enters the apertureor socket 20, and so that the free or headed end of the shank 21 passesthrough the slots or notches 10 of the tumbler disks, to bring theheaded' or shouldered portion 24 within the annular lips or anges 9.Then by'disarranging-the tumblers, by rotating the spindles or shafts 5,the flanges or lips 9 will engage over'the head or shouldered portion 24of the shank 21, and will thus lock the shackle in closed position, theshoulders of the head or portion 24 engaging under the lips or flanges9.

from between the tumbler disks. Thus, the

finger 19 may be withdrawn from the aperture or socket 20 to open theshackle, whereby the shackle may be detached from or applied to a haspkeeper, or any other object, the present device being employed in thesame capacities as an ordinary padlock.

The pin or key 26 engaging the slot 25 of the shank 21 will prevent theshackle from being rotated, and will also limit the outward movement ofthe shackle,in order that the same cannot be detached, although it maybe slid to the necessary extent in opening and closing the shackle.

Ordinarily, when the case is closed, the latch 17 is engaged to the freeend of the section 3 of the case, and will lock the sections inclosedposition.l To change the comdial disks.

bination of the lock, the sections 2 and 3 are opened, by iirst openingthe shackle 18 so that the extension 19 is released from the section 2,the latch 17 also being released from the section 3, to permit the twosec-` tions to swing apart or unfold as suggested in Fig, 1. Then, bywithdrawing the screws or keys 14, after the same have been eX- posed,as seen in Fig. 1, the dial disks may be set to dierent positions or tothe new positions desired, in which event, the screws or keys 14 may bepassed through the apertures 13 alining with the apertures 15 of thetumbler disks, to engage the said apertures 15 for againsecuring thedial disks to the tumbler disks. Thisenables a large number ofcombinations to be had, according Ato the number of indications upon theAfter the dial disks have been readjusted or reset with respect tothetum- .bler disks, the sections 2 and 3 may be closed, and the latch 17then engaged to the free end of the section 3 to lock the sectionstogether under ordinary conditions when it is not desired to open thesections of the case.

From the foregoing, taken in connection with the drawing, the advantagesand capabilities of the present device will be obvious to those versedin the art, without further comment, it being noted that the objectsaimed at have been carried out satisfactorily,

Having thus described the invention what 1.
